No. Name Setting Range Default
Z3-07 Serial Communications Receive to Transmit Wait Time 0 to 99 ms 5 ms
n Z3-08, Z3-09: BACnet Device Object Identifier
These parameters set the Instance Identifier of the BACnet Device Object, where Z3-08 is the least significant word and Z3-09
is the most significant word.
No. Name Setting Range Default
Z3-08 BACnet Device Object Identifier 0 0 to FFFFH 1
Z3-09 BACnet Device Object Identifier 1 0 to 003FH 0
Example 1: Set Device Object Instance Identifier of “1234”.
1234 decimal is equal to 4D2H (hexadecimal).
Set Z3-08 to 4D2H and set Z3-09 to 0.
Example 2: Set Device Object Instance Identifier of “123456”.
123456 decimal is equal to 1E240H.
Set Z3-08 to D687H and set Z3-09 to 12H.
n Z3-10: Cable Loss Pre-set Speed
Sets the frequency reference when a serial communications fault is detected and Z3-05 is set to 4.
No. Name Setting Range Default
Z3-10 Cable Loss Pre-set Speed 0.0 to 60.0 Hz 0.0 Hz
n Z3-11: Communication Fault Detection Selection
No. Name Setting Range Default
Z3-11 Communication Fault Detection Selection 0 to 1 1
Setting 0: Disabled
Ignore setting in Z3-05.
Setting 1: Enabled
Behavior defined by Z3-05.
n Z3-12: Network Digital Input Select
Determines whether the serial communication digital input simulation is active.
No. Name Setting Range Default
Z3-12 Network Digital Input Select 0, 1 0
Setting 0: Disable
Serial communications physical digital inputs are ignored.
For MEMOBUS/Modbus (Z3-01 = 0): Command Register 8402H is disabled.
For Metasys N2 (Z3-01 = 1): Binary Outputs B05, B06, B07, B08, and B09 are disabled.
For P1 Apogee (Z3-01 = 2): Points LDO44, LDO45, LDO46, LDO47, and LDO48 are disabled.
For BACnet (Z3-01 = 3): BV72, BV73, BV74, BV75, BV76, BV77, BV78, and BV79 are disabled.
Setting 1: Enable
Physical digital inputs S1 to S8 are logically OR’d with the serial communications digital inputs.
WARNING! Sudden Movement Hazard. Setting this parameter to 1 may cause the system to run unexpectedly or not stop when required
even if the physical digital input is de-energized, resulting in death or serious injury. Clear all personnel from the drive, motor and machine
area before applying power. Set this parameter to 0 to prevent serial communications from triggering undesired and unexpected system
operation.
